Convertir la lista a la columna Pandas Dataframe

Necesito convertir mi lista en un dataframe pandas de una columna

Lista actual (len = 3):

['Thanks You', 'Its fine no problem', 'Are you sure'] 

Pandas requeridas DF (forma = 3,):

 0 Thank You 1 Its fine no problem 2 Are you sure 

Tenga en cuenta que los números representan el índice en Pandas DF Requerido arriba.

Utilizar:

 L = ['Thanks You', 'Its fine no problem', 'Are you sure'] #create new df df = pd.DataFrame({'col':L}) print (df) col 0 Thanks You 1 Its fine no problem 2 Are you sure 

 df = pd.DataFrame({'oldcol':[1,2,3]}) #add column to existing df df['col'] = L print (df) oldcol col 0 1 Thanks You 1 2 Its fine no problem 2 3 Are you sure 

Gracias DYZ :

 #default column name 0 df = pd.DataFrame(L) print (df) 0 0 Thanks You 1 Its fine no problem 2 Are you sure
